Builder installed magna clean to flow by mistake

[mrbg07546]

my builder said sorry about installing magna clean by mistake. He apologised. I didn't want to make a big deal as he did it for cheap. Is there any point in me getting it changed?

Why is your builder doing work on your heating system?

it's not gas work. Why shouldn't he?

I had a gas installer make the same mistake, but only because he'd connected the F&R wrong at the pump.

The theory behind putting it on the return is that it protects the boiler from dirt in the system. If it's on the flow, all the dirt in the system has to pass through the boiler to get to the filter.

This is why you use plumbers to do plumbing and builders to do building. Buy cheap, buy twice... pay peanuts, get a monkey

It'll also restrict the flow and be exposed to higher temperatures, so not good if it's a plastic one.

Thing is no filter will catch everything on the first pass.

Let's hope it is a sealed system though eh?

I didn't install any filter on my own house.

I guess it's not the end of the world as manual says it can be on flow?

It depends on the system.

You'll be OK then.
